Be it known that I, DAVID P. MILLER, a

citizen of the UnitedStates, residing at Mid-Y dletown, in the county ofDauphin and StateV of Pennsylvania, have invented a new and useful Wrench,vof whichthe following'is a specification. l Y

This invention relates to wrenchesand more particularly t-o pipe wrenches.

wrench of this character which is simple'i'n construction, cheapv f. to manufacture and which will reliablygrip and easily release.

With the foregoing and otherobje'cts' in view, whichY will appear as' the description nation andfarrangement of parts and inthe details ofY construction hereinafter described and claimed, it being understood that,with in the scope of what is claimed, changesv in vthe precise embodiment of the invention shown can loe-made without departing' from; the 'spirit of the invention. j Y' l In the accompanyingV drawings; l

constructed inaccordance withV Vthis' inven-Y tion, parts being broken out for convenience in illustration;

Fig. 2 is a rea-r edge view thereof; and' In the embodimentillustrated, the wrench 1 constituting this invention comp-rises a main body member l having a longitudinally eX;

tending handle 2 at'one end anda laterally extending iXedjaw 3 at its other end. This j aw 3 has biting teeth l o-nits gripping face to cooperate with similar teeth` on the latermovable Vjaw 6. f

The main body l of this wrench has a ally extending gripping member 7 of the recess 5 opening` through V'the `Vrear edge thereof and through its jaw-carrying Vend,

in which is mounted to slide'the movable jaw 6 as is shown clearly in Fig. 1.

The movable j aw 6 is made substantially steel cross bar l0 whiohextends through theopening'Q and limits the sliding movement of the jaw 6 as well as assists in holding it in gripping position by its engagement with The'outerfrear edge Yof the Vlong arm of 1 the aw fis' also' toothed:` afsfshovvnfat;v Sai with which .arev engagedteethlt carried 6 maybe moved' toward 'or awayffroin the :a curved gripping ingeril' whiehisf 'm ount-v f ed on a'spring shank 1l the opposite end-0fA f A said shank being offset inwardly as l'shown 9 at l2 'andrivetedltothelmain body li. jf 'l the'use of Ythis wrenchthe *moi/"ablejav'vlfv Y The object of the 'invention is toprovide a tioned for use infconnection with thepip'e to ybe handled the finger `13 isfagain eng'va'ged.` i 'with the teeth 8% land the resiliencyk ofthez,V f spring shank 1l operates to vforce the v m'ov: if ,able jaw G into'gripping engagement with;` -thepi pe P.
